BALING- PRESS.

SPECIFICATION forming part of Letters Patent No. 671,918, dated April 9, 1901.

Application filed February 16, 1901. Serial No. 47,569. (No model.)

To all whom it may concern.-

Be it known that I, HARRY L. DUNcAN,a citizen of the United States, residing in the city of New York, county of Kings, and State of New York, have invented a new and useful Improvement in Baling-Presses, of which the following is a specification.

My invention relates to presses for forming a cylindrical bale from fibrous material; and it consists in a novel form of positive ejector therefor, by which the forming bale may be discharged from the press positively and at any desired rate, and also in the combination, with a novel form of press, of such an ejector used in connection with the same.

In my copending applications Serial Nos. 47,570 and 47,571, filed February 16, 1901, and Serial No. 48,130, filed February 20, 1901, I claim such of my inventions as are disclosed but not claimed in this case.

In the accompanying drawings, in which similar reference characters refer to the same parts in the several views, Figure 1 is an axial section through a press, showing one form of ejector. Fig. 2 is a detail sectional view, taken on the line 2 2 of Fig. 1. Fig. 1 is a view showing a modified form of ejectorwheel, taken on substantially the central plane of said wheel. Fig. 2* is a view perpendicular to the axis of the press, showing this same ejector-wheel. Figs. 3, 4;, 5, and 6 show another form of ejector applied to various formsof presses, which are shown in axial section. Fig. 7 shows in axial section the ejector disclosed in Figs. 1 and 2 as applied to a press having a conical cap-plate.

In Figs. 1 and 2, Aisastationary cap-plate, having two radial feed-slots a. formed in its top and communicating with the balingchamber below. B is the baling-chamber, substantially cylindrical with a slight taper at the top. It is rotated by an integral gear I), which may be driven at any desired speed byameshiug gear. (Notshown.) Thefiange H at the top of the. chamber serves to hold it in place against the top plate in connection with the collar h, which is screwed thereto. In suitable bearings d on the chamber are mounted a series of four short shafts g, to each of which are rigidly secu red two ejectorwheels E, having teeth and askew-gear G,

as shown. The wheelsE project through the slots D in the chamber and the cylindrical bodies of the wheels and the teeth e thereon are adapted to engage the forming bale in the chamber and force it to rotate therewith and positively feed it therethrough. The gears G mesh with and are rotated by the face gear-teeth on the flange-gear O, rotatably mounted on the chamber B and held in place by the collar 0, secured to the chamber. The gear 0 is rotated at a suitable rate relative to the chamber 13 by gear-teeth on its edge that mesh with a driving-gear. (Not shown.) Just below the collar 0 the bottom plate F of the frame encircles the chamber and forms a bearing for the lower end of the same. Heavy side piecesf connect the capplate A and plate F. The material to be baled is fed to the slots 0. in the usual manner, dragged through them, and compressed against the end of the forming bale, as is usual in this art. The downward pressure of the material under the cap-plate is resisted by the ej ector-wheels E, which so grip the cylindrical forming bale as to prevent it slipping past these wheels. The ejectors are rotated at any rate desired, and thereby regulate absolutely the density of bale formed. The modified form of ejector-wheel E (shown in Figs. 1* and 2*) is adapted to impinge on the body of the bale, passing through the chamber, as is shown in Fig. 2 and the short stub-teeth e are adapted to crowd their way into the surface of the bale without severing the material of which it is formed, as the longer teeth would do. This ejector-wheel is adapted to be mounted upon adriveshaft g in the same manner in which the Wheels E are mounted upon the drive-shaft g.

In Figs. 5 and 6 are shown presses of this same general type for producing a cylindrical bale formed of flat helical ribbons substantially perpendicular to the axis of the bale. They are shown as provided with a rotating ejector-ring through which the forming bale passes having screw-threads formed on their innersurface adapted to engage the bale and to absolutely control the rate at which it moves through the press away from the cap-plate. In Fig. 5 the cap-plate A is stationary and is provided with feed-slots 01. A revolublymounted ejector-ring E is mounted just beneath the cap-plate A and is held against it by a suitable annular abutment on the framepiece F, attached to the cap-plate by bolts, as shown. The gear G is shown integral with the ejector-ring. The inner surface of this ring is conical in contour and is formed with a helical ridge or ejector screw-thread 6 upon it, which is adapted to engage the forming bale and hold it against the cap-plate with the desired degree of force. It is to be noted that the depth of this screw-thread varies. The helical ridge gradually projects farther from the ring into the chamber through the first turn of the thread at the top of the ejectorring. The revoluble baling-chamber B is mounted in a suitable recess in the framing F and ball-bearings are indicated at both of these bearing-points. This baling-chamber has a cylindrical inner surface coaxial with the ejector-ringand is formed with a series of bale-gripping fins g slightly tapered at their upper ends, so as to gradually force their way into the forming bale and projecting inward sufficiently to grip and positively rotate the forming bale at the same speed as the balingchamber. Gear b is shown attached by suitable bolts to the baling-chamber to rotate it at any desired speed when driven by a suitable gear-pinion. The ejector-ring is also intended to be driven at any desired rate by a gear which meshes with the gear-G In Fig. 6 the framework of the machine consists of the piece F which is rigidly attached to the cylindrical baling-chamber B by bolts, as shown. The cap-plate having a substantially fiat lower surface and being formed with feedslots at is revolubly mounted in this framework and is guided so as to be rotated by a gear C shown on the edge of said cap-plate. Just below the cap-plate and also revolubly mounted in the framework is the ejector-ring E, having a driving-gear Gr upon it and having the ejector-screw a formed integral therewith on its inner surface and projecting into the baling-chamber, so as to engage the forming bale and hold it against the cap-plate with the force desired. The ejector-ringis tapered in this case so as to more firmly grip the bale. The stationary baling-chamber B has suitable longitudinal fins g, formed integral therewith on its inner surface, so as to positively rotate the forming bale in unison therewith. It will be noted that these two presses are substantiallyidentical, the only dilference being. in the relative motion of the various parts.

The operation of the press shown in Fig. 5 is as follows: The material is suitably fed to the feed-slots a and is dragged into them and simultaneously compressed against the upper surface of the forming bale, which is positively rotated against the cap-plate by the rotating baling-cham ber 13. The threads of the ejector are pressed into the substance of the bale, so that the bale is prevented from moving through the ejector-ring fast-er than allowed to do so by the screw-feed of the ejector-threads efiand the ejector-ring is made sufficiently long in the direction of the axis of the press, so that these ejector-threads can have this function and so that they will sufficiently impinge on the forming bale to prevent any slip of the bale pastthem. As the bale passes out of the ejector-ring it is engaged by the positively-rotating baling-chamber E the ribs g of which are pressed into the bale-surface so as to insure its positive rotation with the chamber. The rate at which the baling-chamber is rotated determines the number of layers formed in the bale in a given time. The speed at which the ejectorring is rotated determines the amount of feed of the bale through the press, and in an obvious manner therefore determines the bale formed, since as material is draggedinto the feed-slot as long as the bale rotates beneath the cap-plate material will be continually added to the forming bale, so that practically any density is obtainable in this press, and the rotation of the ejector-ring is so regulated as to produce the desired densityin the bale, material being fed constantly, of course, to the feed-slots.

The operation of the press shown in Fig. 6 is almost identical with that just set forth in connection with the press shown in Fig. 5. The various partsthe cap-plate, ejectorring, and baling-chamber--have identical functions, and their forms Will be modified in this press, as in the onejust described, to act properly upon the material to be baled. The density is also similarly regulated by adjusting the relative speeds of the baling-chamher and ejector elements, and the same is true of the press shown in Fig. 1.

In Figs. 3 and 4 I have disclosed a modified form of baling-press in which the cap-plate, instead of having a flat innersurfacc, has an inner surface substantially paraboloidal. This surface is generated by the revolution of a rectangular paraboloid about its axis,thereby forming a surface of revolution the crosssection of which is indicated by the axial section shown in these figures.

In Fig. 3, A represents the cap-plate, having, as shown, a paraboloidal cross-section. Two feed-slots (b are formed on opposite sides of the same on an axial plane. This capplate is stationary and is attached by bolts shown to the framing F which supports in suitable bearings formed by the collar C the baling B Just ahead of the baling-chamberthat is to say, between the chamber and the cap-plate-there is supported by the rear end of the capplate and by the collarf attached to the framing, an ejector-ring E of cylindrical inner surface and mounted eoaxial with the cap-plate and baling-chamber. This ejector has formed thereon the helical screw-thread e, which projects farther and farther into the chamber at the end of the ring nearest the cap-plate throughout the first turn of the thread. The ejector-ring E is adapted to be rotated by theintegral gear G formed thereon. A suitable driving-gear meshes with this gear and is adapted to drive the same at any desired rate of speed. The baling-chamber B, which is adapted to be rotated by the gear 17 attached thereto by bolts, as shown, has formed on its inner surface longitudinal gripping-fins g which extend parallel to the axis of the press and which are adapted to force themselves into the forming bale sufficiently to positively rotate the same with the baling-chamber, which is driven at any desired rate of speed. The operation of this press is as follows: Material is fed into the feed-slot a in any desired manner, and since the forming bale fills the interior of the cap-plate A and presses against the same this bale, rotated by the chamber, serves to drag in additional material through feed-slots 0, which is added to and immediately compressed against the forming bale within the cap-plate. If material is fed constantly to the feed-slots throughout their whole extent, it will be seen that flattened ribbons will be formed which will be compressed against the forming bale within the press and which will assume a form which will conform to the inner contour of the cap-plate, and since these ribbons are continuous and since the bale must necessarily move away from the cap-plate through the press these ribbons will have a helical form-that is to say, they will move about the axis of the press and at the same time move along the axis. Their exact shape in the bale will be substantially a curved surface formed by the revolution of the compressing-abutment of the cap-plate about the bale-axis and its simultaneous uniform feed along the same. This will generate a surface which I call a parabolic helicoid if the com pressing-abutment is a parabola whose axis is the axis of the press. It will be manifest that these continuous layers of fibrous materialsuch, for instance, as cotton-will be at the outer surface of the bale substantially parallel to the bale-axis. This bale, therefore, when completed will be a coherent or self-binding bale. The ribbon layers of which it is composed cannot expand radially because of the circumferential strength of the fibrous material of which they are formed. Also longitudinal expansion is prevented because of the great friction between adjacent layers caused by the great radial pressure exerted in the bale. This bale, therefore, is a coherent mass substantially solid from the moment it is formed justinside the cap-plate, and it is formed continuously as long as material is fed to the feed-slots and the bale rotated by the balingchamber. This bale, therefore, as it moves away from the cap-plate is gripped by the helical threads e of the ejector, which, forcing themselves into the body of the bale, prevent any slip of the halo past them along the axis of the press. The speed at which the'bale can move away from the cap-plate is therefore determined by the rate at which the ejectorring is rotated, because this screw-ejector feeds the bale through the press in exactly the same way in which the screw would feed a solid cylinder of material having a screw-thread cut in it. The bale as it moves through the chamber is positively gripped by the balingchamber fins g, which are pressed into the substance of the bale and firmly hold it against rotation relative to the baling-chamher. The number of layers formed in a given. time, as long as material is constantly fed to the slots 0. throughout their length, depends practically on the speed at which the balingchamber B is rotated. The density of the bale depends upon the speed at which the ejector-ring is rotated relative to the bale, and the bale is therefore given any desired density. This is because material is constantly drawn into the cap-plate and is compressed into a volume determined by the rate at which the ejector displaces the forming bale. It will be noted in this connection that there will be considerable friction of the bale against the inner surface of the cap-plate and against the cylindrical surfaces of the balingchamber and ejector, which will resist the movement of the bale axially to the press. Since the bale is coherent, the ejector can be operated so as to positively force the coherent bale through the press and draw it away from the cap-plate, where the resistance to movement away from the point of the cap plate is greater than the pressure of the capplate upon it, which would tend to force it along the axis of the press. The ejector in the case of the coherent bale therefore posi tively governs the movement of the bale through the press whatever may be the conditions of resistance in the cap-plate. The fins g on the baling-chamber are formed of just sufficient size to properly grip and positively rotate the forming bale with the baling-chamber, and the size of the helical threads a is made just sufficient to give the ejector the proper grip on the bale and control the axial feed of the same through the press. If desired, the relative lengths of the ejector-ring and of the baliug-chamber might be varied without materially affecting their function.

In the press shown in Fig. 4 in axial section the cap-plate A has the same form as that shown in Fig. 3. The inner surface of the cap-plate in both these cases may be made instead of a paraboloid of revolution a helical paraboloid between two adjacent feedslotsthat is to say, such a surface as will be generated by the revolution of a rectangular parabola about its axis and its simultaneous regular feed along its axis. This movement of such generatrix along the axis of the press would be designed so that it would be substantially equal in amount per revolution to the desired feed of the bale through the press per revolution, and in this case the material passing through the feed-slots and being compressed against the parabolic end of the forming bale would be compressed at once to its final form. No rexpansion of ICO ' suitable gear.

this material would be allowed as it moved about the bale-axis until additional material was compressed upon it. In Fig. 4 the cap-plate is secured to the frame F by suitable bolts. The baling-chamber is formed of a cylindrical ring B just behind the capplate and is supported by the ring f secured to the framing. The gear I), integral with the baling-chamber, serves to rotate the same at any desired speed when driven by a (Not shown.) Just back of the billing-chamber B the ejector-ring E is mounted and is held in position by a suitable flange secured to the rear end of the framing F Suitable ball-bearings are indicated for relieving the friction of the moving parts. The ejector-ring is driven by gear G secured to it, and is formed on its inner cylindrical surface with a helical ejector-screw 6 which gradually bites into the cylindrical surface of the bale and absolutely controls its feed through the press. The operation of this form of press is very similar to that shown in Fig. 3. The material fed constantly into the feedslots at is at once compressed against the parabolic head of the coherent forming bale within the press. The bale in this case is positively rotated at any desired rate by the baling-chainber B the longitudinal ribs g of which are just sufiicient in size to prevent rotation of the bale relative to the balingchamber. After passing through the balingchamber the bale is engaged by the ejectorscrew e, which bites into its surface and which prevents any axial slip of the bale past such screw. The bale is fed positively through the press at any desired rate by the revolution of this screw exactly as a solid mass would be. The density of the bale can be controlled in this case exactly as in the preceding form of press described.

In the press shown in axial section in Fig. 7 the cap-plate A is integrally formed with the heavy plate 0 and has its inner surface of substantially conical form. It is provided with two feed-slots a along an axial plane, each extending the whole length of the conical inner surface. A heavy reinforcing-rib is formed around the tip of the cap-plate transverse to the plane of the feed-slots and gives sufficient strength to the cap-plate. The extent of this rib on the outer surface of the cone is indicated by dotted lines. The cylindrical baling-chamber B is rotated by an integral gear I) at any desired speed. The flange I-I is held in place against the plate 0 by the bolted collar h and supports the chamber revolubly against the cap plate and coaxial therewith. A series of four shafts g are mounted in bearings d at the lower part of the chamber. Two spiked ejector-wheels E,whose gripping-teeth e are formed as shown, are fixedly attached to each shaft g, and a skewgear G is also similarly attached to each shaft. These skew-gears all mesh with a large skewgear on the face of C, revolubly held on the end of the chamber by the collar a secured thereto. 0 is revoluble at anydesired rate by gear-teeth on its edge. The plate F supports B revolubly and is supported in turn by rigidly-attached side pieces f, also attached to top plate C The ejector-wheels E project through slots D into the baling-chamber to grip the bale within it. The cylindrical bodies of these wheels impinge on the bale and press longitudinal scores or grooves in it (see Fig. 2) and aside from the teeth a would grip the bale and absolutely prevent its rotation with respect to the chamber. The teeth e also force themselves into the bale and prevent its slipping past them, because these teeth are so large and numerous that the halo cannot tear or crowd past them in moving axially through the press. The form of ejectorteeth shown in Figs. 1 and 2 could be used on this press. The press is operated, after first forming a dummy bale by filling the chamber by hand, as is usual in this art, by constantly feeding fibrous material into the feed-slots a The forming bale within the cap-plate is rotated in close contact with the under surface of the same by the rotating baling-chamberand engages the material outside and constantly drags it through the feedslots and continuously compresses it against the conical end of the forming bale. The bale is therefore built up of continuous flattened helical ribbons, one entering through each feed-slot, that is fed continuously and the surface of which is always inclined to the bale-axis at the same angle that the compressing-lips of the cap-plate are. This bale will be coherent or self-binding, since radial expansion of the bale is resisted by the circumferential strength of the fibrous material of which it is composed, as in the blanket-bale. Longitudinal expansion is prevented by the great friction between adjacent layers caused by the radial pressure exerted through the whole bale. This bale is a coherent mass as soon as it is formed under the cap-plate, and it is engaged and positively fed forward through the press by the ejector-wheels at any rate desired. The ejectors are adapted to either resist the outward axial pressure of the bale caused by the pressure of the cap-plate against it or, in case the frictional resistance of the bale against the chamber and cap-plate exceeds this axial pressure, the ejectors are adapted to positively withdraw the bale from the cap-plate and to pull the coherent bale away from the point of the cap-plate at the rate desired. These ejector-wheels, all of which are rotated in unison, serve to feed the bale axially through the press just as a series of gears would do meshing with a series of racks in a solid cylinder in the baling-chamber. Theejector-wheels form a series of rack-like indentations in the coherent bale and simultaneously feed the bale positively by engaging with these indentations. The density of the bale is regulated by adjusting the relative speeds of the chamber and of the ejectors. Material is constantly fed to the feed-slots a", and as long as the bale is rotated at the same rate beneath the cap-plate the material is drawn in and compressed upon the end of the bale at a practically constant speed. This type of press is self-feeding within wide limits of density of the bale. The axial displacement of the coherent bale by its axial movement away from the cap-plate is governed absolutely by the ejector-wheels, and the volume into which a given amount of material is compressed is thus varied at will. This is the case in all the presses described in this application, and

the density of the material in the bale can be.

practically varied at will.

The presses shown in Figs. 1, 5, 6, and 7 are preferably operated in a vertical position that is to say, with the axis of the press verticalwhile the presses shown in Figs. 3 and 4 are preferably operated with the press-axis horizontal. I wish it to be understood, however, that any form of press can be operated in any position desired and that it is only necessary to give the parts the relative motions I have described and to feed material to the feed-slots constantly in any desired manner.

The rotary bale-governing elements which engage the forming bale and control its axial movement positively govern the axial movement of the bale past them. By positively govern I mean that the rotary governing elements move the bale past them at a definite rate under all ordinary conditions of operation independent of the exact direction or amount of axial pressure which the bale exerts upon such elements and independent of the exact density and physical characteristics of the bale. Where I use the terms positively control, positively feed, and positively move in reference to the axial movement of the bale the word positively has the same significance.

It will be noted that any form of cap-plate shown could be applied to any form of press which I have described in this case. For instance, the press shown in Figs. 1 and 2 could be provided with a cap-plate of parabolic form, such as is disclosed in Fig. 3, or this press might be provided with a substantially conical cap-plate, as is shown in Fig. 7,forming such an ejector-press as is disclosed in my application, Serial No. 48,130, filed February 20, 1901, or, in fact, with a cap-plate having an inner surface substantially of the contour of any surface of revolution and provided with suitable feed-slots along axial planes. A coherent or self-binding bale could manifestly be produced upon this form of press. In any of these presses the bale as it is formed can be suitably bound and covered by means such as is familiar to workers in this art, and which I will not describe, after the continuous cylindrical bale has been severed into suitable individual bales. I do not wish to be limited by the exact proportions of the mechanism disclosed in the drawings in this case, since considerable departure could be made from the exact proportions shown without losing the advantages of my improved construction. The exact scope of my invention will be set forth in the appended claims.
